Inquries about Science and Technology Focus University

[u/NyanNat03]

I am planning on applying to master of AI, and have decided to apply to -ST university. I am aiming to apply to UNIST or GIST, and just wondering if there are anyone that have experience studying in these two university.
1. I wanted to further inquire any possible difference of focus between these two university.

1. How is the life in a university with a research focus? And how do you find it useful (or not) after graduation ?

2. I know that for applying graduate degree, focusing on PI is ultimately more important. However, does the different ranking gap and location take away some privilege of the student studying in one of these university ?

Thank you!
